1310 nm In-line Depolarizer, PM-PM PM Fused Coupler This highly reliable coupler moduleThe depolarizer divides an input beam into two orthogonally polarized beams of equal power. It introduces a delay in one beam before reuniting both using a polarization combiner. The delay exceeds the coherence length of the light source, removing the fixed phase relationship upon recombination.
